IMPROVEMENT IN' SHIPS RUDDERS.

Zo all whom it may concern.'

Be it known that we, THOMAS F. GOODWIN, ED- WARD OOMTED GooDw1N,audCHARLES E. G01N, of the city, county, and State of New York, haveinvented a new aud improved Ships Rudder; and we do hereby declare thatthe following is a full, clear, and exact description thereof, whichwill enable those skilled in the art to make and use the same, referencebeing had to the accompanying drawings, forming part of thisspecification, in which- A Figure l represents a side view, partly insection, of a ship to which'our improved rudder is being attached.

Figure 2 is a side view of. a ship provided with our improved rudder.

Figure 3, is a detail horizontal section of our im'- proved rudder, theplane of section being indicated by the line a: x, fig. 2.

Figure 4 is a detail horizontal section of the same, the plane ofsection being indicated by the line y y,

Similar letters of reference indicate corresponding parts.

This invention relates to a new sectional, removable rudder, which canbe used onall kinds of lmarine vessels, from the smallest row-boat tothe largest steamer, and which is so arranged, that it can be easilyapplied and repaired.

The invention consists in providing the sectional blades whichconstitute the rudder, with devices for fastening the same to therudder-post.

This device consists of a pin pivoted to one end of the section, andfitted through a hole in the post, and of a clasp secured to the otherend of the section, and locked around the post, as will be hereinaftermore fully described.

A, in the drawing, represents the stern of a ship of suitableconstruction.

B is a tube fitted vertically through the vessel, as

shown in iig. l, and firmly and securely fastened in the same.

C is a metal post, or shaft, fitted through the tube, or case B, andresting with its lower end on a shoe, D, as in iig. 2, and with ashoulder, c, formed on it, upon a shoulder, b, of the tube, or upon theupper end of the tube.

Betweenthe shoulders a and b, may frictionrollers,

or spheres be interposed, to facilitate the turning of the rudder-postC.

The post C has, ormay have two or more perforations c c, indicated bydotted lines in g. 1, and a recess cut into it at the end of eachperforation c.

It is also notched, as at el d in fig. l.

E E are the sectional wings, or blades, which, when attached to therudder-post G, as in iig. 2, form and complete the rudder.

Two or more such wings may be used on one rudder.

They are removable from the post, and can be easily attached to thesame.

To the lower part of each' section E, is pivoted a pin, e, by means of apivot, j, as shown in figs. 1, 2, and more particularly iu iig. 4.

To the upper part of each section, is fastened in suitable manner, aclasp, g, which consists of two parts that are hinged together, as iniig. 3, the free part being perforated, so that it can be fitted overand around apin,

or staple, h, that is fastened to one face of the section,

as is also shown in lig. 3.

The pin e of each section is fitted through one of the holes c, and theclasp g around one of the notched parts l of the post, and thus thesection is fastened to the post.

A rudder constructed like that hereinbefore described, can be originallyarranged on a ship, as in g. 2, and will then be very useful andvaluable, as in case a wing, or the whole rudder breaks, the injuredpart can be easily replaced.

The sectional rudder may, however, be carried as safety rudder on a shipwhich is provided with an ordinary rudder, as in fig. l.

In this case, the tube B is provided, and the shoe D made to project, asshown, and the post C can be let down whenever the original rudder Gshould be broken or injured.

The rudder can be secured in the following manner to a ship which isafloat:

. The post (l is by suitable tackle, suspended from a boom, F, and islet through the tube just far enough that its lower end may project, asin fig. l.

The lowermost section E, which is suspended horizontally by suitabletackle, and the pin e of which has been swung to project from the loweredge of the blade, is then by means of guy-ropes i i, brought towardsthe post, so that the pin' e can be inserted in the lowermostperforation c, as in g. 1.

This is done, as shown, above the water-line.

The post is then lowered still further, and the wing E is swung up, andsecured by means of the clasp g.

The'post being still further lowered, the pin e ofthe second sectionbanbe secured, 85e., until all the sections are secured.

It will be noticed that all the sections can he secured above thewater-line, and without much trouble.

We claim as new, and desire to secure by Letters Patent- The sectionalblades E E, which constitute a rudder, provided with pivoted 'pins e,and with clasps y, and locking-devices h, substantially as and for thepurpose herein shown and described.
